FORMAT AND COLUMNS
1. National Stock Number (NSN) Index Work Package. NSNs in this index are listed in National Item
Identification Number (NIIN) sequence.
STOCK NUMBER Column. This column lists the NSN in NIIN sequence. The NIIN consists of the last
nine digits of the NSN. When using this column to locate an item, ignore the first four digits of the NSN.
However, the complete NSN should be used when ordering items by stock number. For example, if the
NSN is 5385-01-574-1476, the NIIN is 01-574-1476.
FIG. Column. This column lists the number of the figure where the item is identified/located. The figures
are in numerical order in the repair parts list and special tools list work packages.
ITEM Column. The item number identifies the item associated with the figure listed in the adjacent FIG.
column. This item is also identified by the NSN listed on the same line.
2. Part Number (P/N) Index Work Package. Part numbers in this index are listed in ascending
alphanumeric sequence (vertical arrangement of letter and number combinations which places the first
letter or digit of each group in order A through Z, followed by the numbers 0 through 9 and each following
letter or digit in like order).
PART NUMBER Column. Indicates the part number assigned to the item.
